Yep the 6502 based micros tended to have more support chips than stuff like the ZX81 and Speccie. I am not sure I would call the VIC-II chip a GPU but it was far more featureful than the Speccie's ULA. Technically the C64 had a 6510 (integrated 6bit IO but in all other senses a 6502). It also had the VIC-II, a 6581 (for sound) and 2 6526s for IO. The Spectrum managed with just a Z80 and the ULA. -- Andy Leighton => an...@azaal.plus.com "We demand rigidly defined areas of doubt and uncertainty!" - Douglas Adams
